Sunny Boy 2500U Installation and Operator’s Manual
SB2500U-11:NE - 11 - SMA Regelsysteme GmbH
Preparing the Mounting
The Sunny Boy is mounted on its back side with the 3 metal straps. For that 3 screws
and 3 according dowels (wall anchors) are necessary. The screws and dowels are
not included. We recommend 6 mm screws and 8 mm dowels.
NOTE: For outside mounting use stainless steel screws. Use a plastic
washer in order to avoid scratching the paint.

Metal straps for mounting: The top straps take the load, the bottom is screwed
down in order to prevent the tilting off the wall.
Mounting to wall
• Mark the holes with the drilling template.
• Drill the holes (and put in the wall anchors), put in the screws of both top holes
and screw them in until ca. 4 mm are sticking out.
• Hang the inverter into the two top screws.
• Fasten the bottom screw. This will prevent lifting of the inverter case.
• Check the mounting of the inverter.
